Microsoft has come under fire from its fans for not adding any major user-facing features in its GDR line of updates, but it seems like that may change with GDR3.

We’ve previously heard that the last Windows Phone update for this year might include more important features, even going as far as including a Notification Center. Now WPDang reiterates those claims, thanks to some unnamed sources, but they also mention that separate volume controls and something called Quick Settings may also be part of GDR3.

Individual volume controls have been a much requested feature ever since the launch of WP7, alongside an orientation lock and easy access to basic settings such as Wi-fi and Bluetooth. And if this rumor turns out to be true we might see all of them show up in GDR3 later this year.

Of course this is still just a rumor for now, and even the original source says that GDR3 is still being worked on with features being added and removed constantly, so you shouldn’t get too excited just yet.
